Description:3-Chloro-2-hydroxy-benzaldehyde, also known by its CAS number 1927-94-2, is an organic compound characterized by the presence of a chlorinated aromatic ring and an aldehyde functional group. This compound features a hydroxyl (-OH) group and a chloro (-Cl) substituent on a benzaldehyde structure, specifically at the 2 and 3 positions, respectively. It is typically a white to light yellow crystalline solid with a distinct aromatic odor. The presence of the hydroxyl group contributes to its solubility in polar solvents, while the aldehyde group allows for reactivity in various chemical reactions, such as condensation and oxidation. This compound is often used in organic synthesis and may serve as an intermediate in the production of pharmaceuticals, agrochemicals, and dyes. Additionally, its chlorinated structure can impart unique properties, such as enhanced biological activity or altered reactivity compared to its non-chlorinated counterparts. Safety precautions should be observed when handling this compound, as it may pose health risks if ingested or inhaled.
